Abstract

An assembled ladder is formed by coupling a top ladder segment, a plurality of middle ladder segments, and a plurality of bottom ladder segments together. The bottom ladder segments include a ladder body, support frame assemblies, ancillary frames, adjustable support pads, and adjustable coupling members. The support frame assemblies are respectively set at two sides of the ladder body. The ancillary frames are mounted to the support frame assembly. The adjustable support pads are screwed to the ancillary frames. The adjustable coupling members have an end coupled to the support frame assemblies and are partially received in the receiving space. With the adjustable coupling members fixing the support frame assemblies, the ancillary frames are expanded. Through adjustment made with the adjustable support pads, the ladder can be set more stably to achieve safety and convenience of use.

Claims

exact text as granted — not AI-modified
I claim: 
     
         1 . An assembled A-shaped ladder, which is an assembled ladder that is formed by coupling together a top ladder segment, a plurality of middle ladder segments, and a plurality of bottom ladder segments, wherein the bottom ladder segments comprise:
 a ladder body, which comprises a receiving space formed therein;   a plurality of support frame assemblies, which has an end coupled to the ladder body, the support frame assemblies being respectively set at two sides of the ladder body;   a plurality of ancillary frames, which is movably mounted to an end of the support frame assemblies that is distant from the ladder body;   a plurality of adjustable support pads, which is screwed to an end of the ancillary frames that is distant from the support frame assemblies; and   a plurality of adjustable coupling members, which functions for adjusting and fixing the support frame assemblies and the ladder body, the adjustable coupling members having an end coupled to the support frame assemblies and an opposite end received in the receiving space.   
     
     
         2 . The assembled A-shaped ladder according to  claim 1 , wherein the top ladder segment and the middle ladder segments each have a lower end that forms a plurality of support legs, the support legs being provided for insertion and fixing for coupling the top ladder segment, the middle ladder segments, and the bottom ladder segments together, the support legs comprising a fixing hole formed therein to receive a mounting bolt to insert therein for coupling purposes. 
     
     
         3 . The assembled A-shaped ladder according to  claim 1 , wherein the ladder body further comprises a plurality of fixing members, which function to fix the adjustable coupling members, the fixing members having an end mounted to the ladder body and adopting eccentric rotation to conduct adjustment and fixing. 
     
     
         4 . The assembled A-shaped ladder according to  claim 1 , wherein the support frame assemblies comprise a first hole and a second hole formed therein at a location adjacent to the ancillary frames, the ancillary frames comprising a corresponding aperture formed therein, the corresponding aperture being selectively set to correspond to the first hole or the second hole to set the ancillary frames in a stowed condition or an expanded condition. 
     
     
         5 . An assembled A-shaped ladder, comprising:
 a top ladder segment;   a plurality of middle ladder segments, which are coupled to the top ladder segment through insertion; and   a plurality of bottom ladder segments, which are coupled to the middle ladder segments through coupling, the bottom ladder segments further comprising:   a ladder body, which comprises a receiving space formed therein;   a plurality of support frame assemblies, which has an end coupled to the ladder body, the support frame assemblies being respectively set at two sides of the ladder body;   a plurality of ancillary frames, which is movably mounted to an end of the support frame assemblies that is distant from the ladder body;   a plurality of adjustable support pads, which is screwed to an end of the ancillary frames that is distant from the support frame assemblies; and   a plurality of adjustable coupling members, which functions for adjusting and fixing the support frame assemblies and the ladder body, the adjustable coupling members having an end coupled to the support frame assemblies and an opposite end received in the receiving space.   
     
     
         6 . The assembled A-shaped ladder according to  claim 5 , wherein the top ladder segment and the middle ladder segments each have a lower end that forms a plurality of support legs, the support legs being provided for insertion and fixing for coupling the top ladder segment, the middle ladder segments, and the bottom ladder segments together, the support legs comprising a fixing hole formed therein to receive a mounting bolt to insert therein for coupling purposes. 
     
     
         7 . The assembled A-shaped ladder according to  claim 5 , wherein the ladder body further comprises a plurality of fixing members, which function to fix the adjustable coupling members, the fixing members having an end mounted to the ladder body and adopting eccentric rotation to conduct adjustment and fixing. 
     
     
         8 . The assembled A-shaped ladder according to  claim 5 , wherein the support frame assemblies comprise a first hole and a second hole formed therein at a location adjacent to the ancillary frames, the ancillary frames comprising a corresponding aperture formed therein, the corresponding aperture being selectively set to correspond to the first hole or the second hole to set the ancillary frames in a stowed condition or an expanded condition.
